There are set from the engine code, not material.
You cannot change queue in material. You can however change queue per object by adjusting translucency sort priority.
I think I had to be more concise. What I wanted to do in a material was this:
Shader “Mask”
{
Properties
{
_MainTex(“Diffuse”, 2D)=“white”{}
}
SubShader
{
Tags{“Queue”=“Geometry-1”}
